CORNET.

Specification of Letters Patent.

Patented Anwar, 1918.

Continuation of application No. 26,419, ileil May 6, 1915. This application led April 16` 1917. Serial To all whom t may concern:

Be it known that I, HENDERSON N. WHITE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented Acertain new and useful Improvements in Cornets, of which the following is a specification.

My invention relates to improvementsA in cornets, and the improvement comprises a simple and effective means for extending and controlling the movement of a tuning slide in such instruments, all substantially as herein shown and described and more particularly7 pointed out in the claims. This application is a continuation of my application for the same subject matter, filed May 6, 1915, Serial Number 26419.

In the accompanying drawing, Figure 1 is a side view of a cornet embodying my invention and shown as tuned in the key A, high pitch. Fig. 2 is an enlarged plan view and part section of the lower portion of the cornet showing the wind pipe, tuning slide and the extensible sleeve therefor completely telescoped and as tuned inthe key of Bb, high pitch. Fig. 3 is a similar view to Fig. 2, showing the slide and sleeve in the same relations to each other but drawn out and set in a diiierent position relatively to the end of the mouth pipe extension or as tuned in the key of A, low pitch. Figs. 4 and 5 are enlarged sectional views of the clamping and stop portions of the tuning Vslide and sleeve. Figs. 6 and 7 are side and end elevations, respectively, of the extensible sleeve alone.

The wind instrument illustrated in the drawings represents a cornet and the invention is particularly applicable to this type of instrument but not necessarily limited thereto. 'As shown, the cornet comprises three valves l, 2 and 3; a bell tube 4; a mouth pipe 5, separate valve slides 6, 7 and 8, respectively; and a tuning slide 9 having two tubular legs 10 and 11 of unequal length in telescopic connection with the straight mouth-pipe extension 12 and the straight branch tube 14 which connects with and is open to valve3, see Fig. 2.. 'Tube 14 and extension 12 are located on opposite sides of the valves and project rearwardly and parallel but at different heights, thereby inclining the crook of tuning slide 9 relatively to the axis of valve 1. A single water key 15 is placed at the beginning of the mouth pipe extension 12.

tained and established in a convenient and positive way by my improvement which .comprises a short clamping tube 16 mounted in slidable' sleeved engagement upon the outer end of pipe extension 12, see. Figs. 2 and 3. Both ends of sleeve 16 are split to provide spring' clamping portions and the inner end is preferably provided with lateral ears 17 and a 'clamping'screw 18, see Fig. 7 whereas the outer end has a slightly enlarged head with a tapered screw thread 19 externally, and an annular shoulder 2O internally, see Fig. 4. A knurled clamping collar 21 is provided with a tapered screwthread internally which is adapted to screw upon the tapered screw threads 19 and in screwing these tapered parts together the split end of tube 16 may be contracted more or less and clamped tightly upon the leg 10 of tuning slide 9. The clamping el'ect produced by collar 21 is usually only moderate and not in itself suiiicient to prevent the withdrawal of slide 9 for a predetermined distance as in making a quick change from Bb to A. The leg 10 of the slide is slightly reduced in `diameter between the crook and the sleeve is in contact with the outer end edge of the pipe extension as seen in Figs. 2 and 4. Then a pull outward on the tuning slide effects a quick change from Bb to A.

But where the requirements call for a different tuning of the instrument primarily, such tuning can be accomplished by relieving the clamping action of the screw 18 and sliding the sleeve 16 outward conjointly with the tuning slide 9. Such shift in vposition of the sleeve upon the extension 12 advances shoulder 20 correspondingly, and slide 9 is still free to move outward the required distance to make a quick change from Bb to A, subsequent to fastening the sleeve 16 by screw 18.

Complete removal of the slide may also be effected in two ways, first, by releasing screw 18 and removing the slide jointlyY with the sleeve from the pipe extension; and second,

by unscrewing collar 21 sufliciently to permit the split portions at the outer or head end of the tube or sleeve to spring outward when engaged by theshoulder 23 and the enlarged portion of leg 10 of the slides, see Fig. 5.

A brief review of the advantages of the adjustable and removable clamping sleeve or member 16 discloses that the instrument can be placed in correct tune very quickly and a quick change from Bb to A made.; that tuning changes of the slide and setting of the sleeve may be accomplished by one and the same movement of the hand and simultaneously; that removal of the sleeve or the slide is easily accomplished; and that the tuning slide and setting sleeve afford a very eiiicient, easily controlled, and compactly related construction which will not get out of order easily or hamper the playing movements of the player of the instrument in any way, but which will in fact facilitate the Vmanipulation of the instrument in a great degree.

What I claim is:

1. In a cornet, a mouth pipe-extension having a tuning slide therein and a sleeve in telescopic connection with both said mouth pipe-extension and slideV and adjustable longitudinally on said mouth pipe-extension, means to adjustably fiX said `sleeve upon said pipe-extension, and means to limit the movement of said slide relatively to said sleeve.

2. In a cornet, a mouth pipe-rextension, a tuning slide in eXtensible connection with said pipe-extension, and a sleeve having a stop to limit the outward movement of said slide and being itself longitudinally adj ustable on said mouth pipe.

3. In a cornet, a mouth pipe extension and a tuning slide therein, and a sleeve in telescopic connection with ysaid slide and adjustable longitudinally upon said pipe-extension having means at opposite ends thereof to adj ustably fix the limits of movement of said parts relatively to each other. i

Il.. In a cornet, a mouth pipe-extension and tuning slide in telescopic connection and a sleeve inclosing the telescopic joint and slidably engaged with both of said parts and removably connected with at least one of said parts', and means to adjustably iX said sleeve upon said pipe-extension.

. nular 5. A cornet having a mouth pipe-eXtension and tuning slide in telescopic connection, a sleeve slidably mounted upon said pipe-extension and having an internal anshoulder at one end thereof to limit withdrawal of said slide from said pipe-extension, and means to fasten said sleeve adjustably upon said pipe-extension.

6. A cornet having a mouth pipe-eXtension and tuning slide in telescopic connec# tion, a sleeve slidably mounted upon said pipe-extension having a split end slidably engaged with said slide, a clamping device to hold said split end in working engagement with said slide, and meansl to fasten said sleeve adjustably in different positions longitudinally upon said `pipe-extension.

7. A cornet comprising a mouth pipe eX- tension and a tuning slide therein, itsl end closely fitting in the extension, a short tube having a smooth internal surface slidably mounted at one end upon said pipe extension and in telescopic connection at its other end with said tuning slide and having a shoulder internally to limitthe withdrawal movement of said slide.

8. A cornet having a mouthfpipe eXtension and a tuning slide having a shouldered end closely fitting in said extension, a short sleeve slidably mounted upon said pipe eX- tension having a split end provided with an internal shoulder to engage said shouldered end, a clamping collar encircling saidsplit end, and a device to fasten said sleeve in various adjusted positions on said pipe.

9. A cornet comprising a mouth pipe eX- tension and a tuning slide in telescopic connection therewith, a sleeve upon said mouth pipe extension having both ends split to pro-V vide spring portions, and separate means at each split end to clamp the sleeve upon said pipe extension and slide, respectively.

10. A cornet comprising a mouth pipe eX- tension having a tuning slide telescoped therein, a split sleeve in extensible connection with said pipe extension having a shoulder in stop relation with said slide, a clamping screw'to fiX said sleeve upon said pipe extension, and a screw collar encircling said HENDERSON N WHITE.
